Well the yellowing is certainly progressing through the levels of leaves. First it was the big fans on the main stalk, now it has moved to the fans on the individual branches, and soon enough it will be the main leaves around the buds. That is how it has always progressed in my past grows, and my harvest has been not even close to what it should be.

My room does get a little hot, topping out around 89 if I forget to open my night time curtian on a hot day. Other than that and the week or so where the pH might have been +.5 I can't think of what the issue would be. It seems that moving it into the larger container didn't help the problem. The roots are still healthy and white. I'm not sure what else to do. Where is Weedhound when you need her?
